I think you are missing a key thing in this deck, removal. And you have some awesome removal at your disposal, I would say 4 copies of
shivan fire, and mayber 2 or 3 copies of
Fight with Fire.
Fight with Fire is awesome because if you do get to kick it you can just aim it at their face for game. I would also say cut
run amok,
fling,
krosan druid and maybe warlords fury, and
wild onslaught. I would also play 4 hallar, and some amount of verix blade wing. verix is only like 2$ so he isn't going to blow your budget. also Grand Warleader Rahda is pretty good in a kicker deck and you definantly want 4 elfhame druids because this deck is going to be really mana hungry. A lot of the ramp creatures are elves so Marwyn seems pretty good. you could drop her and play
grow from the ashes. also maybe play 4
shivan fire and 2 lighting strike or go 3 and 3 or cut
abrade and go 4 and 4 its up to you. I would also add
fight with fire to my list for sure.
I built a deck similar to this awhile back this is my list. Idk what your budget is but this is around 60$ to cut down the budget get rid of
sheltered thicket, and
rootbound crag for
evolving wilds, and
timber gorge.
Here is my build
